The Development of Binuclear Au, Pd, and Pt Complexes for Aqueous Phase Hydroamination Catalysis Donald A. Krogstad, Department of Chemistry, Concordia College Moorhead, MN 56562 Binuclear Complexes as Catalysts: Multinuclear metal complexes have shown great promise as N N organic transformation catalysts. P P N Presently, there is a need to prepare Br N Br N N P “green” water-soluble analogs of these N NH4PF6 PF6PF6N + N 2 N systems and to utilize their catalytic N potential. Therefore, we have used bis-phosphines that contain two PTA moieties to prepare bimetallic, water-soluble catalysts. Initial studies of the Au, Pd, and Pt complexes indicated N that the multinuclear species exhibit enhanced catalytic activity for the intramolecular H C C (CH2)3 NH2 hydroamination reaction in water when compared to their monometallic analogs. Additionally, it was shown for the first time that Au may be a superior choice for this important aqueous phase C-N bond formation reaction.
